| Before Verizon rolled out its nationwide 5G service using dynamic spectrum sharing last year, its mmWave deployments delivered speedy results with the tradeoff of barely any coverage. Earlier testing by Ookla showed the carrier’s 5G speed took a hit as the carrier started leaning on lower band spectrum, and Verizon found itself at the bottom of the pack in RootMetrics latest speed rankings.However, T-Mobile, which has been touting its rollout of high-capacity 2.5 GHz mid-band spectrum, was close by. It clocked median download speeds between 50-100 Mbps in 11 markets – just one more than Verizon. That’s still a big improvement over the second half of 2020, when T-Mobile clocked 50-100 Mbps in just two of the 45 markets.AT&T didn’t hit that benchmark but took the lead with median download speeds of at least 50 Mbps in 31 markets, and none that registered below 25 Mbps. AT&T’s nationwide 5G service uses lower band spectrum including 850 MHz, with limited mmWave deployments largely focused on venues and high density locations.5G network rankings often vary across testing companies, which employ different methods for collecting and analyzing data. For example, in new Speedtest results from Ookla, T-Mobile reigned in Q1 for 5G speeds and time spent on 5G. According to Ookla, T-Mobile clocked median download speed of 82.53 Mbps, which compares to AT&T (76.6 Mbps) and Verizon (67.24 Mbps). -- ???????? | |||
